Optofluidic technologies

Demetri Psaltis, James Adleman

Optofluidics refers to adaptive systems that integrate optical and fluidic devices. Micro and nano-fluidics enable novel devices which introduce liquids into optical structures. We discuss recent optofluidic developments, including optically powered vapor ...

An integrated holding-beam-at-transparency (hbat) configuration for semiconductor optical amplification or emission

Benoît Marie Joseph Deveaud, Andrea Crottini, Marc-André Dupertuis

An optical device for amplifying or emitting an optical beam of given wavelength comprises an optical source (20) in combination with a primary optical device (10) which is a semiconductor optical amplifier (SOA), a gain-clamped semiconductor optical ampli ...

Mechanically tunable optofluidic distributed feedback dye laser

Demetri Psaltis

A continuously tunable optofluidic distributed feedback (DFB) dye laser was demonstrated on a monolithic replica molded poly(dimethylsiloxane) (PDMS) chip. The optical feedback was provided by a phase-shifted higher order Bragg grating embedded in the liqu ...

Coupled photonic crystal microcavity array laser

Hatice Altug

We designed a new laser composed of two-dimensional coupled photonic crystal microcavity arrays. In these structures we have observed single mode lasing with power conversion efficiency 10 times better than a single microcavity laser. ...

Study of vertical coupled-cavity laser structures

This thesis addresses general aspects of the operation of a coupled-cavity vertical surface-emitting laser (CC-VCSEL) which consists of two active cavities optically coupled and independently electrically pumped. The first two chapters of the thesis deal w ...

Photosensitivity and bragg grating technology for upconversion all-fiber lasers

Marcel Zeller

Fiber lasers are compact lightsources with high intrinsic beam quality and high efficiency. The lasing spectrum ranges from the blue to the near infrared and is achievable using fibers with different dopants and glass compositions. All-fiber lasers are cha ...

Optical properties of In(Ga)As/GaAs quantum dot-based devices emitting at 1.3[mu]m

Self-assembled quantum-dots (QDs) represent a distributed ensemble of zero dimensional structures with a near-singular density of states. Implemented as the active medium in a diode laser their unique properties lead to improved and often novel characteris ...

Highly efficient one- and two-cascade Raman lasers based on phosphosilicate fibers

René Salathé, Hans Georg Limberger, Florian Dürr, Marcel Zeller

Characteristics of one-cascade (1.06 double right arrow 1.24 mum) and two-cascade (1.06 double right arrow 1.24 double right arrow 1.48 mum) phosphorus-doped fiber Raman lasers are studied. The cavities of both lasers are formed by Bragg gratings written d ...
